Engine management and monitoring
The engine monitoring system continuously analyzes the operating data of the engine. When limit values are
violated, the system initiates engine protection features. This ensures operational availability and long the
service life of the engine.
The engine management system controls e.g. the injection timing, injection duration and the resulting injec-
tion quantity for each ignition and for each cylinder. It controls, among other thing, the speed and high-pres-
sure fuel. The engine management system minimizes consumption and exhaust gas emissions and maximiz-
es power.
Key new features for the engines in this series include the Engine Control Unit ECU 9 (engine governor).
Engine governor ECU 9
The engine governor is the central control and monitoring unit of the engine.
It features a robust and shock-proof design and is mounted directly on the engine.
